FEED-WATER HEATER.

SPECIFICATION forming part of Letters Patent No. 330,650, dated November 17, 1885.

Application tiled December 9, 1884. Serial No. 149,828.

'fo all whom it may concern.'

Be it known that I, SAMUEL J. WEAVER, of the city of St. Louis, in the State of Missouri, have invented acertain new and useful Improvementin Feed-Water Heaters, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specication, and in which- Figure l is an elevation or side View of my improved feeder. Fig. 2 is a vertical section of same. Fig. 3 shows the device applied to an outside receiver, from which the boiler is fed. Fig. ,4 is a vertical section of a trap to prevent steam entering the supplypipe.

My present invention relates to an improvement on Letters Patent N o. 304,679, issued September 2, 1884, to myself and assignee, Jno. OBrien; and this invention consists in features of novelty hereinafter fully described, and pointed out in the claims.

Referring to the drawings, A represents part of a boiler, and B the .feed-pipe.

C represents a tank into which the water is discharged from the feed-pipe. It has a screw -threaded neck, D, by which it is scoured to the pipe, or it may be secured by other suitable means. It has openings I for the escape of the water, as indicated by'arrows, Fig. 2, and above these openings is a hood, J, that deects the water as it escapes through the openings I.l The hood is held down by a collar, L, tting on the feed-pipe between the hood and the boiler. The feedpipe extends down into the tank, so that it is submerged in the water therein, and thus steam is prevented from entering the supplypipe and cracking it, while the feed of the water is notinterfered with. On the outside of the tank I prefer to cast flanges or ribs N, increasing in size downward, over which the water falls, dropping from one to another through thesteam, which causes it to be thoroughly heated before it falls to the water in the boiler. The tank, including its neck D and flanges N, is cast in one piece of metal, and the part of the supply-pipe that extends down into the tank is preferably dis- (No model.) A

connected from the main length, as shown at O, Fig. 2, and formed in one piece with the collar L.

Fig. 3 represents how the feeder may be applied to a separate tank or receiver, from which the boiler is supplied with warm water inthe usual manner, through a pipe, P, the steam from the boiler entering the receiver through a pipe, T. The tank or receiver has a man-hole, W. f

In Fig. 4 a modified form of trap is shown, which consists in turning the end of the supply-pipe upward, forming a water-trap, V, that will effectually prevent steam entering the supply-pipe.

The tank is preferably larger at its lower than at its upper end, so that it is in the form of a frustum, and the flanges N could be dispensed with, though I prefer not, as the water will run down the outside ofthe tapering tank, and will not be discharged directly into space from the openings I.

My improved device acts to purify the water, as well as to heat it.

I claim as my invention- 1. In a boiler feeder and purifier, the cornbination of the feed-pipe and tank, the latter having flanges on its outside increasing in size downward, substantially as and for the purpose set forth.

2. In a boiler feeder and purifier, the combination of the feed-pipe and tank, the former being submerged in the latter, and the latter having flanges increasing in size downward, substantially as and for the purpose specified.

8. In a boiler feeder and purifier, the combination of the feed-pipe and a tank having openings for the escape of the water, and external flanges or ribs projecting into the steamspace, substantially as set forth.

4. In a boiler feeder and purifier, the combination of the feedpipe, tank, and hood, the tank having openings beneath the hood for the escape of water, and having flanges or ribs increasing in size downward, substantially as and for the purpose set forth.

5. In a boiler feeder and purifier, the combination of the feed-pipe and tapering-tank having discharge.- openings, substantially as toconical tank, openings in said tank near set-forth. its upper or smaller end, and a hood projeet- Io 6.
